When I try to create an account it’s required personal details first then i try to type my date of birth it’s something wired like ggggggg

Hi. Welcome.
Are you using an English keyboard? No translation app or anything in the way?
Tagging you incase its an app error, caused by an update? 
All the other times it’s been language related.
Could also be that the phone is set to use a non-Gregorian calendar in Settings > General > Language & Region > Calendar, given that I think it’s asking for an Era (the GGGGG pattern).
Everyone should brush up on their Date Format Patterns.
Thank you so much 
It’s working
